Task List/pkrs lv5

Wow! Seems like you need to have an extremely low immune system to catch Pokérus 500 times. You should still be clicking the host though, it's that... good kind of sickness.

Click the "Pokérus" button in the top right corner beneath the bonus counters (on the mobile site, you must click the arrow in the bottom right corner, then click "Pokérus" under the bonus counters) to go to the host's page. The more you click the host, the better your chances of catching Pokérus.

For more information on Pokérus, check the Wiki.
